Okay kiddo, so you know how sometimes people elect someone to be the leader of their country, like the president? Well, in some countries, they have something called an "eternal president".
Now, when we say eternal, we don't mean that the president is going to live forever (which would be pretty cool!). Instead, it means that they hold the position of president for their entire life, and even after they die, they are still considered the president.
This might sound a little strange to you. After all, if someone isn't alive anymore, how can they still be president? Well, sometimes in these countries, the people in charge want to make sure that one person has all the power and influence, and they don't want anyone else to take over.
So, they create this idea of the "eternal president" to ensure that the leader they choose will always be in charge, even after they die. This can be pretty controversial, because it means that no one else gets a chance to run the country, and the people don't get a say in who their leader is.
Some people like the idea of an eternal president, because they believe it provides stability and continuity to their country's government. Others think it's not fair, because it means that one person has all the power, and that power can be abused.
Overall, an eternal president is a pretty complicated topic, and a lot of different factors go into why a country might choose to have one. But now you have a basic understanding of what it means!
